Application Novembelr'20, 1934, Serial No.753,928 f 1 Claim.

IThis invention relates to squares. An object of the invention is to provide a square of a novel construction so that it combines with a square the function of a level, a plumb, a miter square and a bevel square. I

Another feature of the invention is the provision of a relatively thick straight edge on one side of the main leg by folding the body portion of the main leg over the reinforcing blocks.

Further objects of the invention are to provide a square of the character referred to that is strong, compact and durable, formed of metal that will not rust, that is comparatively ineX- pensive to manufacture and thoroughly reliable for its intended purposes.

With the foregoing and other objects in View the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings, wherein is provided the preferred form of the invention, but it is to be understood that changes, variations and modifications may be resorted to without departing from the spirit of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a top plan view of the obverse face of the square showing the blade thereof extended.

Figure 2 is a view similar to Figure 1 showing the reverse side thereof.

Figure 3 is an end elevation of one end of the square.

Figure 4 is a transverse, detailed vertical section, taken substantially on line 4-4 of Figure 2.

Figure 5 is a fragmentary edge view of an end of the main leg of the square.

Figure 6 is a view similar to Figure 5 but taken at right angles thereto and having a portion thereof shown in section.

Referring to the drawings in detail, A indicates the main leg of the square and B indicates the short leg of the square, said legs being joined together to form a right angle. The obverse face 'l of the main leg is flat and divided by the lines 8 into a scale in inches. The obverse face of leg B is likewise flat and is indicated at 9. This face is also divided by the lines I0 into a scale of inches. The main leg A and the short leg B are preferably formed integral with each other and may be made of any type of metal that will not rust such as aluminum, copper or brass. 'I'he obverse face of the main leg and the short (cia3-89) II leg are flat and lie in the same plane. Intermediate the ends, the main leg is formed with a rectangular opening I I through which the bubble tube I2 may be viewed from the obverse face.

There is a diagonal connecting arm I3 connecting the main leg A and the short leg B and the plane of this connecting arm is the same as the obverse face l of the main leg and the obverse face 9 of the short leg; The connecting arm I3 is connectedwith an intermediate portion of short leg B and also connected with an intermediate portion of the main leg A. The connecting arm I3 permits the use of the .square as a miter square and also acts to brace the two legs and hold the square true. The inner edge of the short leg B is formed with serrations I4 the inner point I5 of which corresponds with the scale markings on the obverse face 9 thereby permitting this portion of the short leg to be used as a marking gauge.

The reverse face of the main leg is indicated at I6 while the reverse face of the short leg B is indicated at I'I. Along .the outer margin the metal of themain leg A is folded back upon itself in a rectangular configuration, thereby providing a relatively wide edge I8 that serves as a straight edge, a at bottom I9 and the inner edge 20 all of which are integral with one another. Between these folds I8, I 9 and 20 is a pocket 2| of substantially rectangular configuration in which is carried the reinforcing wooden blocks 22. These blocks are held in position by rivets 23.

At the upper end of the main leg a bubble tube 24 is carried in thepocket 2|, the pocket 2l being open at this end. The bubble tube has one end mounted in a collar 25 and the other end in a collar 26 which collars are secured respectively to outer straight edge I 8, and inner edge 20. The bubble tube 24 extends transversely of the main leg A and may be easily seen from the upper end of the square since the tube is mounted adjacent the free edges of the rectangular fold.

There is a recess 2'I formed in the fold of the main leg A in which is mounted the bubble tube I2. The recess 2l is in alignment with the opening I I and the tube I2 disposed under the opening I I. One end of the tube is mounted in a bracket 28 which is secured to the reverse face I6 while the other end is likewise secured in brackets 29.

The inner end of a at metal blade 3l) swings on the shank of a screw 3| carried by the lower end of the main leg A. When the blade 30 is adjusted to any desired angle it may be locked in position by the wing nut 32 on the screw 3l.

PATENT VvolerloE The blade 30 is flat and the outer free edge 33 thereof is diagonal. The inner edge 2D of the rectangular fold is provided With a slot 34 into which the blade 30 is folded when not in use. 'I'he Wooden reinforcing block 22 does not extend into that portion of the fold of metal in the path of the blade therefor the blade may be folded into a portion of the pocket. The blade 30 is the same in Width as the flat portion of the main leg A. The blade 3D enables the square to be used as a bevel square and does not interfere with the use of the square because it may be folded out of the Way.

The serrations I 4 on short leg B provides `aV ruling gauge by placing the point of a pencil in the notch and rplacing the square on the edge of the timber; the timber may be marked to the scale l0 on the opposite edge.

Having described my invention, what I claim as new is:

A square comprising a right-angled metal body portion and including a main leg fiat on the obverse side and a short leg at on both sides which legs are joined together at the apex of the angle, the metal of the main leg being folded over back- Ward on the reverse side along the outer margin into a substantially rectangular coniiguration providing a pocket and forming a relatively thick straight edge on the outer edge of the main leg whereby the main leg resting on the thick edge may be used in horizontal position as a level and in the vertical position as a plumb, a pair of bubble` tubes carried by the main leg one transversely of and the other longitudinally of the main leg to function as indicators in the plumbing and levelling positions, and the transverse bubble tube situated in the pocket at a point Where the main leg joins the short leg so that the tube may be viewed from the end of the leg.
